adjusting laser power?
« on: December 01, 2016, 07:31:31 AM »
im guessing the answer is no but is'nt there ANY way to adjust the laser power with benbox software?
i wish i could just weaken the laser a little when doing detailled/small work so it does'nt just burn/carve everything!
cheers :)

Not easily. The best you can do is increase the speed, but they have the maximum fairly low so you're restricted.

Hi, Zax,

I have the same problem. I saw a thread where you say it can be changing some jumper and flashing some other thing, but I canīt find it now.

Do we need to get a new board to accomplish that?. Because at 2.5W it mostly burns everything

Thanks!

If you use BCL or T2Laser you can, but not with Benbox.

In my signature below, click the "Download" or "Updates" link and you'll see a file called "T2Laser_Conversion4.pdf", you will need to follow that to enable PWM control of the laser. Basically move the jumper and install a newer Grbl.

Here's a direct link:
